This is my Design and patent named Billboard bench. Billboard bench is the new medium of outdoor advertising. Innovation is its use-value. When a Billboard bench is not used for seating, the seat is in a vertical position and reveals an area for advertising. When used for seating, the seat is in a horizontal position. After using the bench, the seat itself back into a vertical position under the influence of gravity, and reinvents the advertising area.Unlike most "multi-practices"solutions, Billboard bench combines two functions on the advanced mode, in which no billboard or bench "does not stumble" with each other. On the contrary, Billboard bench brings new features such as:-Taking up little space in the exterior and interior (waiting rooms, bus and metro station)-The seat is dry after rain, and snow days.Because of these advantages, Billboard bench is a very useful commercial product, which aims to provide citizens a quality and a modern bench. The city will not spend the funds for setting up new and maintaining old seat, but the bench to earn funds for the city.
